Other storage

[theprizerevealed]

I am using macos Catalina 10.15.4 and my Other storage is 140 GB. I don't have many files on my hard drive, maybe 10 GB maximum. Nor do I use Time Machine. It's been disabled since I bought my iMac. I used the terminal code

 du -sh *

in the home directory I believe it's called (the one that appears when you start the terminal program.

This was the output

I saw that the Library folder was 134 gigabytes so I switched to that folder and repeated the command

However I see only the Developer which is 132 gigabytes

How do I fix this issue and what is the developer folder about?

This is what's inside the developer folder

109G    CoreSimulator
1.7G    XCPGDevices
145M    XCTestDevices
21G    Xcode

Why is the CoreSimulator using so much space?


This is what's inside the Coresimulator folder

4.4G    Caches
104G    Devices
  0B    Temp

okay, I solved this problem (mostly) after I went into the Devices folder. I saw there were a bunch of devices registered there. So, I googled and found this website https://stackoverflow.com/questions/34910383/xcode-free-to-clear-devices-folder

which told me to use this command

 xcrun simctl delete unavailable

This reduced drastically the number of registered devices in that folder. So when I checked again About Mac it shows that I recovered more than 80 GB from other. I will leave this here to help other people with a similar problem

Open the app called Terminal then paste in that command and hit the return key.
